Boundary of the area contributing flow to the Death Valley regional ground-water flow system, Nevada and California

This digital data set defines the boundary of the area contributing ground-water flow to the Death Valley regional ground-water flow-system (DVRFS) model domain. The boundary encompasses an approximate 112,000 square-kilometer region and was based on a map of regional potential developed by Bedinger and Harrill (2004). Where possible, the amount of lateral flow across the segments of the DVRFS model boundary from (or to) the contributing area was estimated from ground-water budgets of hydrologic units in the adjacent subregion (see "Larger Work Citation", Appendix 2). The lateral ground-water flow estimates were used to support development of the transient ground-water model of the DVRFS completed in 2004 by the USGS (see "Larger Work Citation", Chapter F).

本数字数据集划定了为死亡谷区域地下水流系统（Death Valley Regional Ground-Water Flow-System，DVRFS）模型域提供地下水流补给的区域边界。该边界覆盖约112000平方千米的区域，其编制依据为Bedinger与Harrill于2004年绘制的区域地下水势分布图。在可行范围内，本数据集通过邻近亚区域内水文单元的地下水均衡计算，估算了补给区与DVRFS模型边界各分段之间的侧向地下径流量（流向为从补给区流入模型域或由模型域流出至补给区）。上述侧向地下径流量估算结果，可为美国地质调查局（United States Geological Survey, USGS）2004年完成的DVRFS非稳定地下水流模型的研发提供支撑（详见"大型成果引用"附录2与第F章）。
